RELEASE-NOTES-1.24

   1 Security reminder: MediaWiki does not require PHP's register_globals. If you
   2 have it on, turn it '''off''' if you can.

   4 == MediaWiki 1.24 ==
   5
   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.24 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.24 ===
  12 * The server's canonical hostname is available as $wgServerName, which is
  13   exposed in both mw.config and ApiQuerySiteInfo.
  14 * Introduced $wgPagePropsHaveSortkey as a backwards-compatibility switch,
  15   for using the old schema of the page_props table, in case the respective
  16   schema update was not applied.
  17 * $wgSearchEverythingOnlyLoggedIn was removed as the 'searcheverything'
  18   user option was removed. Use $wgNamespacesToBeSearchedDefault instead or
  19   if you used to have $wgDefaultUserOptions['searcheverything'] = 1.
  20
  21 === New features in 1.24 ===
  22 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
  23   WhatLinksHere entries.
  24 * Added a new hook, "ContentGetParserOutput", to customize parser output for
  25   a given content object.
  26 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
  27 * HTMLForm's HTMLTextField now supports the 'url' type.
  28 * HTMLForm fields may now be dynamically hidden based on the values of other
  29   fields in the form.
  30 * HTMLForm now supports multiple copies of an input field or set of input
  31   fields, e.g. the form may request "one or more usernames" without having to
  32   have the user enter delimited list of names into a text field.
  33 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
  34   the sidebar just before its display.
  35 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
  36   jQuery.cookie so that getting/setting a cookie is syntactically and functionally
  37   similar to using the WebRequest#getCookie/WebResponse#setcookie methods.
  38 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1.
  39 * Changes to content typography (fonts, etc.). See
  40   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  41 * WikitextContent will now render redirects with the expected "redirect"
  42   header, rather than as an ordered list. Code calling Article::viewRedirect
  43   can probably be changed to no longer special-case redirects.
  44 * Header font set to a serif font stack. See
  45   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  46 * (bug 63903) Thumbnails without an explicit size specification are
  47   now resized to a square bounding box. This gives better results for
  48   non-landscape thumbnails.
  49 * (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of the HTTP
  50   to HTTPS redirect due to forceHTTPS cookie, userRequires, etc.  This is only for page views,
  51   since this hook doesn't affect UserLogin, OAuth, CentralAuth, etc.
  52   ATTENTION: This hook is likely to be removed soon due to overall design of the system.
  53 * (bug 17367) It is now possible to add pages to your watchlist from
  54   Special:UnwatchedPages without reloading the special page.
  55 * New methods setVolatile and isVolatile are added to PPFrame, so that
  56   extensions such as Cite.php can mark that their output is volatile and
  57   shouldn't be cached.
  58 * (bug 52817) Advanced search options are now saved on the search page itself, rather
  59   than in a dedicated pane in the preferences panel.
  60
  61 === Bug fixes in 1.24 ===
  62 * (bug 49116) Footer copyright notice is now always displayed in user language
  63   rather than content language (same as copyright notice for editing interface).
  64 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  65   restriction was present in the parameters.  Images with both the "frame"
  66   option and a size specification set will now always ignore the provided
  67   size and display an unscaled image, as the documentation has always
  68   claimed it would.
  69 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  70   which used to collapse some sidebar elements by default.
  71   This removes -list id suffixes like p-lang-list: instead of using things like
  72   #p-lang-list, you can do #p-lang .body ul.
  73 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
  74   follow redirects to their target pages.
  75 * Parser now dies early if called recursively, instead of producing subtle bugs.
  76 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
  77   remaining page content.
  78 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
  79   in the file namespace and delete the file on the target page. It will still
  80   however delete the redirect page.
  81
  82 === Web API changes in 1.24 ===
  83 * action=parse API now supports prop=modules, which provides the list of
  84   ResourceLoader modules that should be used to enhance the parsed content.
  85 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
  86   field which is true iff protocol-relative urls can be used to access
  87   a particular interwiki map entry.
  88 * ApiQueryLogEvents now provides logpage, which is the page ID from the
  89   logging table, if ids are requested and the user has the permissions.
  90 * action=edit now requires that appendtext, prependtext, or section=new be used
  91   when using the 'redirect' parameter, to prevent clients accidentally
  92   overwriting the target page with the content of the redirect.
  93 * action=logevents will now return an error if both letitle and leprefix are
  94   specified.
  95 * action=logevents has a new parameter, lenamespace, to allow filtering by
  96   namespace.
  97
  98 === Languages updated in 1.24 ===
  99
 100 MediaWiki supports over 350 languages. Many localisations are updated
 101 regularly. Below only new and removed languages are listed, as well as
 102 changes to languages because of Bugzilla reports.
 103
 104 === Other changes in 1.24 ===
 105 * The deprecated jquery.delayedBind ResourceLoader module was removed.
 106 * The deprecated function mw.util.toggleToc was removed.
 107 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
 108   were removed as they were unused.
 109 * (bug 65477) User::pingLimiter() now has an additional profile point varying
 110   by action being used.
 111 * mediawiki.util.$content no longer supports old versions of the Vector,
 112   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
 113   and/or "mw-body-primary" class name in their html.
 114 * Added pp_sortkey column to page_props table, so pages can be efficiently
 115   queried and sorted by property value (bug 58032).
 116   See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 117 * BREAKING CHANGE: The Modern and Cologne Blue skins were moved out of MediaWiki
 118   core to their own respective repositories. See also
 119   https://www.mediawiki.org/wiki/Skin:Modern and
 120   https://www.mediawiki.org/wiki/Skin:CologneBlue.

 163 == Compatibility ==
 164
 165 MediaWiki 1.24 requires PHP 5.3.2 or later.
 166
 167 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 168 support for them is somewhat less mature. There is experimental support for
 169 Oracle and Microsoft SQL Server.
 170
 171 The supported versions are:
 172
 173 * MySQL 5.0.2 or later
 174 * PostgreSQL 8.3 or later
 175 * SQLite 3.3.7 or later
 176 * Oracle 9.0.1 or later
 177 * Microsoft SQL Server 2005 (9.00.1399)
 178
 179 == Upgrading ==
 180
 181 1.24 has several database changes since 1.23, and will not work without schema
 182 updates. Note that due to changes to some very large tables like the revision
 183 table, the schema update may take quite long (minutes on a medium sized site,
 184 many hours on a large site).
 185
 186 If upgrading from before 1.11, and you are using a wiki as a commons
 187 repository, make sure that it is updated as well. Otherwise, errors may arise
 188 due to database schema changes.
 189
 190 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 191 new database fields are filled with data.
 192
 193 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 194 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 195 with MediaWiki 1.21.
 196
 197 Don't forget to always back up your database before upgrading!
 198
 199 See the file UPGRADE for more detailed upgrade instructions.
 200
 201 For notes on 1.22.x and older releases, see HISTORY.
 202
 203 == Online documentation ==
 204
 205 Documentation for both end-users and site administrators is available on
 206 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 207 for pages that explicitly state that their contents are in the public domain):
 208
 209         https://www.mediawiki.org/wiki/Documentation
 210
 211 == Mailing list ==
 212
 213 A mailing list is available for MediaWiki user support and discussion:
 214
 215         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 216
 217 A low-traffic announcements-only list is also available:
 218
 219         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 220
 221 It's highly recommended that you sign up for one of these lists if you're
 222 going to run a public MediaWiki, so you can be notified of security fixes.
 223
 224 == IRC help ==
 225
 226 There's usually someone online in #mediawiki on irc.freenode.net.
